Abstract

L'invention concerne un dispositif d'injection de carburant comprenant une pompe haute pression (10) et un injecteur (12) par cylindre du moteur thermique, cet injecteur étant relié au moins indirectement à la pompe haute pression (10) par un conduit hydraulique (26;27). L'invention est caractérisée en ce que chaque injecteur (12) est relié par un conduit hydraulique (26;27) à la pompe haute pression (10) et/ou à l'injecteur (12) d'un autre cylindre du moteur thermique. Il est ainsi possible de supprimer l'accumulateur de haute pression qui se trouve habituellement entre la pompe haute pression (10) et les injecteurs (12).
